Results of two studies, involving surveys of alumni of postsecondary institutions, are presented to assess the effect of format and typeface on mail survey response rates. The first study focused on the effect of booklet/folder format versus stapled sheets. The method of reproduction, page content, page size, and appearance of the questionnaires were identical. Subjects were 100 former students of the University of Tennessee. The second study involved use of: (1) a questionnaire version produced by a laser printer that allowed variation in type size; and (2) a version originally produced by a typewriter and photocopied. Subjects were 297 former students of the same university. In each study, each subject received only one of the two form types. Results of the studies are consistent with previous findings that when the same questions are used, there is no significant difference between questionnaires of different lengths, between questionnaires with a professional appearance (typeface) and those that are typed, and between booklet and stapled questionnaires. It is noted that, due to the narrowness of the subject scope of the studies, generalizations from these conclusions should be made cautiously. (TJH)
